Desiccant Cartridge Replacement

I have an 11 year old motor home with approx. 35000 miles on it. Having read some inputs via the forums, The potential of a desiccant cartridge in my Bendix air dryer breaking up and causing a very expensive cleanup has me thinking that maybe I should replace it as a preventative measure, DIY cost approx. $170.

I am not interested in just throwing $170. into the wind but would like some advice from readers of this forum.

You need to change the filter and desiccant. I failed to do mine in a timely fashion and I had engine oil dripping out of the bottom of the dryer. I first thought something broke in the compressor but when I changed the filter everything was ok. I was told at a truck center that failure to change the filter would cause it to pump oil. My dryer is a Haldex and the filter kit was $132 at my local NAPA store.

The option I use is to get a Bendix factory reman (NOT reman by Bubba or his friends). That way the factory overhauled it and replaced, not only the filters but also heater, valves, etc. Not much more money if you figure your time as worth anything.

After I changed mine in November I was at Bontraggers in Michigan the first week in December and found a complete Haldex dryer, never been installed, they wanted $200 and I offered $150 and they took it. It had been setting for some time because I saw it last summer but didn't know I needed it. I installed it complete and took my old one and removed the filter and all the other new parts and put it back in the box so now a have a complete kit for next time.
